Abstract: The present application relates to a polarization separation element, a method for manufacturing a polarization separation element, a device for irradiating light, a method for irradiating light, and a method for manufacturing a photo-alignment layer. An ultraviolet ray polarization separation element, according to the present invention, has superior resistance to ultraviolet rays and heat, and involves a simple manufacturing process due to less pitch dependency of polarizing characteristics. In addition, the polarization separation element according to the present application can achieve a superior degree of polarization and extinction ratio even within a short wavelength field.
